BitScope performs data capture according to a selected trace mode.
The trace mode controls how many analog channels to capture and what type of timebase to use. It also applies an optional pre and/or post trigger delay to allow data before and/or after to trigger to be captured.
Five registers are used to program the trace mode:
The most important trace mode register is the Trace Register R8. The low 4 bits of this register are programmed to with a Trace ID to select one of 6 available modes:
The values to program to the other trace mode registers depend on the selected mode. Also, the upper 4 bits of the Trace Register R8 are reserved and should always be programmed as zero.
